Micronaut Platform 4.7.0

Core

Micronaut Core contains multiple improvements. To highlight a few, it improves the HTTP Client implementations, the display of circular dependency errors, adds a new API FilterBodyParser, the possibility to disable normalization of property keys in @EachProperty beans, and it adds nicer HTML error pages.

LangChain4J

Micronaut LangChain4J provides integration with Langchain4j.

For example, Micronaut LangChain4J makes easy to inject your favourite language model in your Micronaut beans:

import dev.langchain4j.model.chat.ChatLanguageModel;
import jakarta.inject.Singleton;

@Singleton
class DefaultJokeGenerator implements JokeGenerator {
    private final ChatLanguageModel model;
    DefaultJokeGenerator(ChatLanguageModel model) {
        this.model = model;
    }

    @Override
    public String generateJoke() {
        return model.generate("Tell me a joke about Java?");
    }
}

GraalPy

Micronaut Graal Languages is a collection of components for integration of Graal based dynamic languages with Micronaut Framework.
